Hello,

Am currently running into an nsim problem and not sure if this is a fumefx for maya issue. I am simulating a major pyroclastic smoke effect and am attempting to optimize my scene. I created my master grid matched all the resolutions of my nsim grids, overlapped them and made sure they're accurate. As soon as my simulation enters the nsim grid outside of my master grid, not only does my simulation not carry into the new grid, my entire scene crashes. Any ideas or help with this issue?

I've been trying to get the camera to move through or even close to smoke and no matter what I do I can't get a good clean edge to the smoke. It always looks blurry. I've experimented, I think, with all the settings and while I can get great looking smoke at distance I can't seem to get as sharp a close up as I would expect.

I know this is incredibly vague but I've tried to many different options to really post anything specific. I've included an example.

Any advice would be appreciated.

Hi guys i wanted to use effector in a way when for example smoke goes thru sphere effector and after that it triggers force (for example gravity, or with or whatever)

Do you thing is possible to implement this feature (because now i cant use efector to drive "Use" button in obj/src rolout)

Thanks a lot

1) Smoke color that I select in the Render tab doesn't render anything except black. This hasn't happened before.

2) When I run the sim, smoke and fire show in the preview window, The mr renderer shows fire and smoke as just a black blob. An error message -- 448 MB error: Object < FumeFX001 > has invalid texture vertices and may not render correctly.

I'm running 3.5.2 with Max 2013.

Help would be appreciated

Thanks.

Hi, at first I was trying to figure out how to render out smoke emitting from an object so that the smoke hidden behind the object doesn't show (as it should in real life).

I tried using Use Background, Surface Shader, etc. and played around with matte opacity values.... still cant figure out how to do it. Surely this problem is extremely common & obvious... as fumefx is almost useless with "emit from object".


then later I realized no matter where the smoke is...or what shader I have on any objects in front....the fumefx smoke will always be in front.


what's going on here?.. very frustrating lol :STABRE

I have a sim here (fire only) that loses detail after applying a render warp. Even before the warp is deformed to alter the cache shape. I've never caught this before - perhaps it's been occurring all along and wasn't apparent.

Occurs with both an FFD and Bend. Haven't tested other warps. Applies to both default and wavelet cache, and tested in both Scanline and Vray.

A before/after shows what looks like the voxels being smoothed or averaged.

Kresimir, I emailed you separately - sorry for the double post.

Hi Guys we are using newest fumefx 3.5.3 but there is still problem with motion blur and vray. We cant get any motion blur with this renderrer, it is poosible to fix it

Thanks a lot

Hello,

Is that possible in any way to change playback speed of
smoke after complete simulation at render time ???

Thank you

Hi!

I didn't have any issues with FumeFX before but after a hardware switch to an Alienware 18 it has started to crash all the time and it seems to be totally random. Sometimes its just when I select the FumeFX-node, sometimes when I'm simulating etc. Anyone with the same issue? Any ideas?

Cheers

Hi,

I think I must be doing something wrong

I have a simulation of 30 frames, than I use the frame 30 as initial state for another simulation, all good so far.
But if I start wavelet simulation on top I see nothing. The caches are there and they are big, unfortunately nothing render at all

in steps
1: run a sim of 30 frames (default cache)
2: take frame 30 of sim 1 as initial state for sim 2
3: run sim 2 (defauls cache) ALL good
4: run wavelet of sim 2... big caches, no smoke render

Thanks for any help!
